A new study has identified a group of neurons that, when activated, can induce a hypometabolic state, akin to hibernation. The discovery could have far-reaching implications for conditions like obesity, cardiometabolic diseases, and even for space travel. The research team found that these neurons regulate key aspects of the brain-heart-gut axis.

Experiments have yielded a fascinating new type of matter, neither granular nor crystalline, that responds to some stresses as a fluid would and to others like a solid. The new material, known as PAM (for polycatenated architected materials) could have uses in areas ranging from helmets and other protective gear to biomedical devices and robotics.

Following two months of record heat and precipitation in fall 2022, an estimated 7,500 lakes in West Greenland turned brown, began emitting carbon and decreased in water quality in less than a year. The spike in temperatures caused the precipitation to fall as rain instead of snow. The heat also caused permafrost to thaw, releasing an abundance of carbon, iron, magnesium and other elements that the rain washed into the lakes. Researchers found a decrease in phytoplankton that absorb carbon dioxide from the atmosphere through photosynthesis within the lakes, and an increase in plankton that break down and release carbon. Instead of sequestering carbon dioxide in the summer, the lakes have become a source of it, with a 350% increase in the flux of this greenhouse gas from them.

Fast radio bursts are mysterious and brief flashes of radio emissions that were thought to be produced by magnetars, highly magnetized rotating neutron stars. Yet magnetars appear primarily in young star clusters. A repeating burst discovered last year has been pinpointed to the distant outskirts of an old but massive elliptical galaxy where, theoretically, such stars would long since have disappeared. Does this mean magnetars are not the source of FRBs?

A brain-computer interface, surgically placed in a research participant with tetraplegia, paralysis in all four limbs, provided an unprecedented level of control over a virtual quadcopter -- just by thinking about moving his unresponsive fingers.

Marine scientists highlights the complex interplay between heat stress, disease onset and coral mortality. They found that 66 percent of the colonies were bleached by February 2024 and 80 per cent by April. By July, 44 percent of the bleached colonies had died, with some coral genera, such as Acropora, experiencing a staggering 95 percent mortality rate.

Scientists have developed a computing chip that can learn, correct errors, and process AI tasks.

A first-of-its-kind study shows that while teams with differing skill sets and perspectives bring fresh, unique ideas to the table, they often struggle to create practical, workable solutions -- raising important questions for managers and businesses worldwide.

A new study provides compelling new evidence that a colossal 'megaflood' refilled the Mediterranean Sea, ending a period during which the Med was a vast expanse of salt flats. The study suggests the Zanclean Megaflood ended the Messinian Salinity Crisis, which lasted between 5.97 and 5.33 million years ago.

Antibiotics, antivirals, vaccinations and anti-inflammatory medication are associated with reduced risk of dementia, according to new research that looked at health data from over 130 million individuals.
